Jerusalem Artichoke: Benefits, Culinary Uses, and Growing and Care Techniques

Today we are recommending a plant commonly known as the "insulin fruit" - the Jerusalem artichoke (Helianthus tuberosus), a member of the Asteraceae family, genus Helianthus. Some flower shop owners also call it "devil's ginger" or "foreign ginger." It originated in North America, and later spread to China because of its strong adaptability and its cold- and drought-tolerant characteristics. It was subsequently found to have good medicinal value in lowering blood sugar, strengthening the spleen and benefiting the stomach, and removing dampness, and it is now cultivated in most regions of China.

The Jerusalem artichoke is a herbaceous plant, and its roots closely resemble the shape of ginger. After growth, its flowering period is concentrated in August to September each year, and the blooms are usually pale yellow or yellow. If you want to grow it, you can buy the plant at a flower market, with a height of about 1 m to 2 m, and in spring some farmers also bring out its tubers to sell. Whether you take home tubers or a potted plant, it is relatively easy to care for in daily maintenance.

The Jerusalem artichoke is naturally cold-tolerant, drought-tolerant, and tolerant of poor soil. Even in an environment as low as minus 40 degrees, it can still survive vigorously. At the same time, its root system has strong fibrous roots, and when planted in the ground its roots go very deep, so its drought tolerance is very good.

As for soil, because the Jerusalem artichoke is a plant with tenacious vitality, it is not very picky about soil. Apart from acidic soil, swamps, and saline-alkali areas, which are not suitable for planting, it can grow relatively well in most ordinary garden soil. It also has very few diseases, because its root system contains components such as helianthol and bisabolene, and this is the smell that insects fear most. In addition, after planting, the Jerusalem artichoke does not need the trouble of replanting, because its roots can firmly hold the soil, making it a once-and-for-all choice.

As for watering, although the Jerusalem artichoke has strong survival ability, from the modern pursuit of high-quality plant growth, it is recommended that the soil can remain in a state of alternating dry and wet for a long time. Usually, during the seedling stage, flower bud stage, tuber expansion stage, and jointing stage, a high soil moisture level is needed.

In addition, besides its medicinal value, the Jerusalem artichoke can also be used in fields such as food additives, alcohol, health products, and beverages. In terms of food use, there are quite a few ways to eat it: it can be stir-fried, steamed, boiled, or served as a cold dish, and after cooking it has a crisp and sweet taste.
